   •  O IA

10. Refer to the exhibit. What tin be concluded about network 192.168.4.0 in the R2 routing table?

    

    CCNA3 v6.0 Chapter ix Exam 001

    •  The network was learned from a router within the same area as R2.
    •  The network was learned through summary LSAs from an ABR.
    •  The network tin be reached through the GigabitEthernet0/0 interface.
    •  This network should be used to forward traffic toward external networks.

11. Which three steps in the design and implementation of a multiarea OSPF network are considered planning steps? (Choose iii.)

    •  Verify OSPF.
    •  Configure OSPF.
    •  Define the OSPF parameters.
    •  Assemble the required parameters.
    •  Troubleshoot the configurations.
    •  Ascertain the network requirements.

12. Which two networks are part of the summary route 192.168.32.0/22? (Choose two.)

    •  192.168.31.0/24
    •  192.168.33.0/24

    •  192.168.36.0/24
    •  192.168.38.0/24

13. Refer to the exhibit. What is indicated by the O IA in the router output?

    

    CCNA3 v6.0 Chapter 9 Exam 004

    •  The route was manually configured.
    •  The route was learned from within the area.
    •  The road was learned from outside the internetwork.
    •  The road was learned from another surface area.

14. Refer to the exhibit. A network ambassador has been asked to summarize the networks shown in the exhibit as part of a multiarea OSPF implementation. All addresses are using a subnet mask of 255.255.255.0. What is the correct summarization for these eight networks?

    

    CCNA3 v6.0 Chapter 9 Exam 003

    •  10.0.4.0 255.255.0.0
    •  10.0.0.0 255.255.240.0

Which command should the administrator use to forward the summary road for area xv into expanse 0?

    •  area 0 range 172.16.eight.0 255.255.255.248
    •  area 0 range 172.16.8.0 255.255.248.0

    •  expanse 15 range 172.16.8.0 255.255.255.248

16. Friction match each type of OSPF router to its description. (Not all options are used.)

    

    CCNA3 v6.0 Chapter ix Exam 01

17. Fill in the bare. Do not utilise acronyms.
    OSPF type two LSA letters are only generated by the designatedrouter to annunciate routes in multiaccess networks.

18. Fill up in the blank. Employ a number.
    An ASBR generates blazon five               LSAs for each of its external routes and floods them into the area that information technology is connected to.

19. Fill in the blank. Utilize a number.
    A blazon four               LSA identifies the ASBR and provides a road to it.

20. Refer to the exhibit. Fill in the blank. Do not employ abbreviations.
    The network 192.168.x.128 0.0.0.127 area 1 command must be issued to configure R1 for multiarea OSPF.​

21. Open the PT Activeness. Perform the tasks in the activeness instructions and then answer the question.
    Why are users in the OSPF network not able to access the Net?

    •  The default road is non redistributed correctly from router R1 by OSPF.
    •  The interface that is continued to the Isp router is down.
    •  The OSPF network statements are misconfigured on routers R2 and R3.
    •  The OSPF timers that are configured on routers R1, R2, and R3 are not compatible.
    •  The network statement is misconfigured on router R1.

22. Open the PT Activity. Perform the tasks in the activity instructions and and so answer the question.
    Make full in the blank. Do not utilise abbreviations.
    What is the missing command on router R2 to establish an adjacency between routers R1 and R3? network 172.16.ten.0 0.0.0.255 area 0 .
